Setting the Exposure<br />
Effect of Aperture<br />
Adjust the amount of light hitting the CCD by changing the aperture.<br />
Opening the aperture (reduce the aperture value)<br />
Objects closer and farther than the focused subject will be more<br />
out of focus. For instance, if you take a picture of flower against<br />
a landscape with the aperture open, the landscape in front and<br />
behind the flower will be blurred, emphasizing only the flower.<br />
Closing the aperture (increase the aperture value)<br />
The range in focus expands forward and backward.<br />
For instance, if you take a picture of flower against a landscape<br />
with the aperture narrowed, the landscape in front and behind<br />
the flower will be in focus..<br />
Depth of Field<br />
When you focus on a portion of the subject, there is a range in which object closer and farther will<br />
also be in focus. This focused range is called the <strong>de</strong>pth of field.<br />
The <strong>de</strong>pth of field for the <strong>GX</strong>-<strong>1L</strong> differs <strong>de</strong>pending on the lens but compared to a 35 mm<br />
camera, the value is roughly one aperture setting lower (the focused range becomes narrower).<br />
The wi<strong>de</strong>r the wi<strong>de</strong>-angle lens, and the farther away the subject, the wi<strong>de</strong>r the <strong>de</strong>pth of field is<br />
(some zoom lenses do not have a scale for <strong>de</strong>pth of field because of their structure).<br />
